The ozone contained in this mixed stream is used by the pretreatment tank 5, The odors such as hydrogen sulfide (H2S) and ammonia (NHs) emitted from the sewage treated in the adjustment tank 6 and the aeration tank 7 are divided, added, and oxidized to try to reduce the odor. [Problems to be Solved by the Invention] However, the half-life of ozone in the atmosphere is about 13 hours. Inside the wastewater treatment facility, as described earlier, the reaction of oxidizing odorous components emitted from sewage by ozone The speed is not fast, and the time required for the reaction between ammonia and ozone is long, and it cannot be fully reacted in a limited time due to these reasons. In the drainage treatment facility shown in Figure 4, the emissions from the sewage The odor component cannot be completely oxidized by ozone, so the odor component and ozone are discharged to the outside from the exhaust pipe 4 to diffuse the odor to the outside of the drainage treatment facility. In addition, although there is a spray nozzle that mixes ozone and water and sprays it out, it generates hydroxyl radicals (0H radicals) that are more active than ozone. Using this hydroxyl radical to oxidize odorous components has achieved the purpose of odor removal. However, the ozone generating means such as the ozone generator 11 has a pressure of the ozone stream that is lower than 1 kg / cm2. Therefore, using only the ozone stream that is emitted by the ozone generating means, water cannot be passed through the spray nozzle. Sprayed out like a mist, so no hydroxyl radical β can be generated (please read the precautions on the back of Jing before filling this page) This paper size applies Chinese National Standard (CNS) A4 Washing (210X297 mm) -6- Printed by the Central Standards Bureau of the Ministry of Economic Affairs, Shellfish Consumer Cooperative 414782 a7 __B7___ V.
